Pesquisa do Estado de Minas Gerais (FAPEMIG) Acacia mangium Willd. (Fabaceae) ? uma esp?cie pioneira, de r?pido crescimento e rusticidade, al?m de apresentar potencial nitrificador, sendo utilizadas em programas de recupera??o de ?reas degradadas. Os objetivos deste trabalho foram estudar a evolu??o na recupera??o de ?rea degradada utilizando-se plantas jovens de A. mangium, sua produ??o de produ??o de massa foliar e de seus insetos e aranhas como bioindicadores (abund?ncia, diversidade e riqueza de esp?cies) e as intera??es entre os grupos de artr?podos, durante 24 meses. O delineamento experimental foi inteiramente casualizado com 24 repeti??es (plantas jovens), sendo os tratamentos o primeiro e o segundo ano ap?s o plantio. As plantas de A. mangium, no segundo ano de desenvolvimento, apresentaram maiores n?meros de folhas/galho, galhos/?rvore e de cobertura do solo (serapilheira, plantas herb?ceas e gram?neas), abund?ncias de Hemiptera Phenacoccus sp. (Pseudococcidae) e Pachycoris torridus Scopoli (Scutelleridae); Hymenoptera Tetragonisca angustula Latreille e Trigona spinipes Fabricius (Apidae) e Brachymyrmex sp., Camponotus sp. e Cephalotes sp. (Formicidae); Blattodea Nasutitermes sp. (Termitidae) e Neuroptera Chrysoperla sp. (Chrysopidae); e maiores abund?ncias e riquezas de esp?cies de insetos polinizadores e de formigas cuidadoras, e abund?ncia de predadores de Sternorrhyncha comparada com o primeiro ano. Maiores abund?ncias de Hemiptera Aethalium reticulatum L. (Aethalionidae), Hymenoptera Camponotus sp., Cephalotes sp., Polybia sp. (Vespidae), T. angustula, T. spinipes, e abund?ncias de formigas cuidadoras, insetos polinizadores, predadores totais e de Sternorrhyncha e riqueza de esp?cies de formigas cuidadoras foram observadas em plantas de A. mangium com mais folhas ou galhos. As maiores abund?ncias de T. spinipes e de Pheidole sp. se correlacionaram de forma positiva com aqueles de A. reticulatum; as de Tropidacris collaris Stoll. (Orthoptera: Romaleidae) e de Parasyphraea sp. (Coleoptera: Chrysomelidae) com as de Araneidae. As maiores diversidade e riqueza de esp?cies de Hemiptera fit?fagos incrementaram aqueles de predadores de Sternorrhyncha e a abund?ncia de insetos mastigadores a de aranhas. Por outro lado, as maiores abund?ncias de insetos mastigadores apresentaram correla??o negativa com as de Bemisia sp. (Hemiptera: Aleyrodidae); as de formigas cuidadoras com as de T. spinipes e as de Dolichopodidae (Diptera); e as de predadores totais com as de T. spinipes. A idade das plantas de Acacia mangium influenciou no aumento da popula??o de artr?podes e cobertura do solo, indicando ser uma boa alternativa para a recupera??o de ?reas degradadas. Disserta??o (Mestrado) ? Programa de P?s-gradua??o em Biologia Animal, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2021. Acacia mangium Willd. (Fabaceae) is a pioneer species, with rapid growth and rusticity, in addition to presenting nitrifying potential, being used in programs for the recovery of degraded areas. The objectives of the work were to study the evolution in the recovery of degraded area using A. mangium saplings, its production of production of leaf mass and of its insects and spiders as bioindicators (abundance, diversity and specie richness) and as interactions between groups of arthropods for 24 months. The experimental design was completely randomized with 24 replications (saplings), with treatments being the first and second years after planting. The A. mangium saplings, in the second year of development, had higher numbers of leaves/branch, branches/saplings and soil cover (litter, herbaceous and grass plants), abundance of Hemiptera Phenacoccus sp. (Pseudococcidae) and Pachycoris torridus Scopoli (Scutelleridae); Hymenoptera Tetragonisca angustula Latreille and Trigona spinipes Fabricius (Apidae) and Brachymyrmex sp., Camponotus sp. and Cephalotes sp. (Formicidae); Blattodea Nasutitermes sp. (Termitidae) and Neuroptera Chrysoperla sp. (Chrysopidae); and greater abundance and specie richness of pollinating insects and tending ants, and an abundance of Sternorrhyncha predators compared to the first year. Greater abundances of Hemiptera Aethalium reticulatum L. (Aethalionidae), Hymenoptera Camponotus sp., Cephalotes sp., Polybia sp. (Vespidae), T. angustula, T. spinipes, and abundance of tending ants, pollinating insects, total and Sternorrhyncha predators and specie richness of tending ants were observed in A. mangium saplings with more leaves or branches. The highest abundances of T. spinipes and Pheidole sp. correlated positively with those of A. reticulatum; and those of Tropidacris collaris Stoll. (Orthoptera: Romaleidae) and that of Parasyphraea sp. (Coleoptera: Chrysomelidae) with those of Araneidae. Greater diversity and specie richness of Hemiptera phytophages increased those of Sternorrhyncha predators and an abundance of chewing insects to spiders. On the other hand, the highest abundance of chewing insects was negatively correlated with of Bemisia sp. (Hemiptera: Aleyrodidae); that of tending ants those of T. spinipes and Dolichopodidae (Diptera); and that of total predators with those of T. spinipes. The greater age of the A. mangium saplings, increased the arthropod populations and soil cover, indicating that it is a good alternative for the recovery of degraded areas.
